bad batt or alt?

doubt it car will run fine with the system off.

have you tested either one of them? otherwise get a bigger batt or alt and see how that helps

lights are dimming because of your electrical. its either your alt or battery or you just REALLY need a bigger alt. it helps a lot if you post what you are using and dont write off peoples advice.

we need to know your car, amps, ohm load, total power, what volume they dim at, size of wire.

edit- with the system off, the car is running the way it was designed to. if you add a bigger draw then the electrical isnt made to keep up with it.

Depending on the vehicle that could be the voltage regulator

too much power draw. 1400wrms=100amps. your alt is 110A. probably need a bigger alternator. and a better battery.
